I’m thrilled about the encouraging gene therapy results just published in Science Translational Medicine from Paola Leone, PhD and R. Jude Samulski, PhD, and colleagues. “Long-term follow-up after gene therapy for Canavan Disease” updates a project that has its origins in the mid 1990s. Canavan disease is a brain disorder present from birth.

I’ve been following some of the kids who’ve had the gene therapy. One patient in particular – Max Randell – has been in my human genetics textbook since age three, his progress updated with each edition.  Read More 

The excerpt below supplements the blog entry that is beneath it and also at Public Library of Science. It is from The Forever Fix: Gene Therapy and the Boy Who Saved It, (St. Martin's Press, 2012).


I sat at a table with Paola, Mike, Max and Max’s charming little brother Alex, who was eight going on twenty-eight. While the adults ate chicken alfredo (except for vegetarian Paola) and the kids downed chicken fingers and fries, Mike leaned over Max, pulled up his shirt, and deftly attached a bag of cream-colored stuff to the feeding tube coming from his son’s stomach, holding it aloft for the food to go in. At the front of the ballroom, Ilyce, svelte in a shimmering blue gown, was getting ready for her annual thank-you. Read More 

Max Graduates!

Tomorrow night, Max Randell will graduate from middle school. He even passed a test on the U.S. Constitution. I don’t think I could do that.

Max has Canavan disease. And thanks to gene therapy, he’s here to celebrate.

Canavan disease is an inherited disease that strips the insulation from nerve cells in the brain. It destroys neural function, beginning at birth and likely before, and the child loses the battle by age 8 -- unless she or he has gene therapy, still experimental (as are all gene therapies).  Read More
